Description

The present invention relates to a bath device capable of disinfecting hot water in a bathtub.

As a specific example of the conventional bath device, there is one described in Patent Document 1.
The bath device described in the same document is a hot water circulation path that is connected to a bathtub and enables hot water in the bathtub to be circulated by a certain route by driving a circulation pump, and a hot water circulation path provided at an intermediate position of the hot water circulation path. Equipped with a fungus device. The sterilizer has a housing having an inlet and an outlet for hot water flowing through the hot water circulation path and a hot water distribution section formed inside, a sterilizing lamp arranged in the housing, and the sterilizing lamp. It is equipped with a protective cover that covers the area around the disinfectant lamp so that it does not come into contact with hot water. The protective cover has a translucent property that transmits ultraviolet rays for sterilization emitted from the sterilization lamp, and by driving the sterilization lamp to light up, the hot water in the housing is irradiated with the ultraviolet rays, and the hot water is radiated. Is sterilized.

In the bath device as described above, since hot water comes into contact with the outer surface of the protective cover, this portion is liable to become dirty. When the outer surface of the protective cover becomes dirty, the ultraviolet transmittance of the protective cover is lowered, and the amount of ultraviolet irradiation to hot water is reduced, so that the sterilization treatment ability is lowered. Therefore, in Patent Document 1, a cleaning device for cleaning the outer surface of the protective cover is provided. This cleaning device is equipped with a cleaning rotating body equipped with a brush that contacts the outer surface of the protective cover, and can move up and down along the axial length direction of the protective cover while rotating the cleaning rotating body. is there.

However, in the above-mentioned prior art, there is still room for improvement as described below.

That is, the stain on the protective cover can be caused not only by the dirt such as foreign matter in hot water directly adhering to the protective cover, but also by the growth of various germs in the housing of the sterilizer. Specifically, the sterilization treatment may not be executed for a long time, and hot water may remain in the sterilization device. In such a case, various germs grow in the sterilization device. There is a risk of When germs grow in the disinfectant, the surface of the protective cover of the disinfectant lamp becomes dirty with germs. In this case, the ultraviolet transmittance (ultraviolet irradiation efficiency for hot water) of the protective cover is lowered, and the sterilization treatment capacity is also lowered.

On the other hand, the sterilization device in Patent Document 1 is only configured to operate when a predetermined switch operation is performed by the user or when a timer is set in advance by the user. As described above, various germs may grow in the sterilization device, and the stain may cause a problem that the sterilization treatment ability is lowered. In Patent Document 1, in order to prevent the problem, it is necessary to pay attention to the user to operate the sterilizing device frequently, but this increases the burden on the user and is inconvenient.

Further, in Patent Document 1, when the protective cover of the sterilizing device becomes dirty due to the growth of various germs, the cleaning device is operated to clean the protective cover. Dirt caused by proliferation does not easily come off, unlike mere adhesion of foreign matter, and even if the cleaning device is operated, it is difficult to clean the protective cover in its original clean state. Therefore, it is inevitable that the sterilization treatment capacity is reduced due to the dirt on the protective cover.

As another example of the bath device, there is one described in Patent Document 2.
The bath device described in the same document is configured to be suitable for use as a so-called 24-hour bath, and the sterilizing lamp of the sterilizing device is continuously driven for a predetermined time at the initial stage of operation, and then sterilized. The fungus lamp is controlled to be driven on intermittently at a predetermined cycle. With such a configuration, it is possible to prevent the growth of various germs in the housing of the sterilizer.
However, in Patent Document 2, since the sterilization device is merely turned on and off at a predetermined cycle, for example, the sterilization process is executed by operating the operation switch after the user finishes bathing. After that, the sterilization treatment may be repeated immediately after that, which may cause waste. This not only increases the running cost of the device, but also causes a problem that the service life of the disinfectant lamp is shortened (the more frequently the disinfectant lamp is switched on and off, and the longer the lighting time is, the longer the disinfectant lamp is used. Generally, the service life is shortened).

Japanese Unexamined Patent Publication No. 10-128316 Japanese Unexamined Patent Publication No. 9-164089

The present invention has been conceived under the above-mentioned circumstances, and prevents germs from multiplying inside the sterilizing device to cause stains, and the sterilization treatment is caused by the stains. The challenge is to provide a bath device that can appropriately solve problems such as reduced capacity.

In order to solve the above problems, the following technical measures are taken in the present invention.

The bath device provided by the first aspect of the present invention includes a hot water distribution section through which hot water in the bathtub can flow in and out, and a disinfectant lamp capable of irradiating the hot water in the hot water distribution section with light for disinfection. It is a bath device including a sterilizing device having a sterilizing device and a control unit for controlling the sterilizing device, and the control unit is said to be said when the drive-off state of the sterilizing lamp continues for a predetermined time or longer. The disinfectant lamp is configured to be temporarily driven on, and even if the disinfectant lamp drive-off state continues for the predetermined time or longer, the hot water of the hot water distribution unit is used during that period. When is replaced with another hot water, the temporary drive-on operation of the disinfectant lamp is not executed, and the temporary drive-on operation of the disinfectant lamp is the disinfectant lamp. It is characterized in that both the drive-off state of the above and the state without replacement of hot water in the hot water distribution section are executed when the predetermined time or more continues .

According to such a configuration, the following effects can be obtained.
First, if the drive-off state of the disinfectant lamp continues for a predetermined time or longer, the disinfectant lamp is driven on, so that the growth of various germs in the hot water distribution section of the disinfectant device is appropriately prevented. .. Therefore, it is possible to prevent the inside of the sterilization device from becoming dirty due to the growth of various germs, and to preferably eliminate the problem that the irradiation efficiency of the sterilizing light for hot water is lowered.
Secondly, the temporary drive-on operation of the disinfectant lamp described above is performed automatically by the control of the control unit. Therefore, it is possible to reliably prevent the growth of various germs in the hot water distribution section of the sterilizer without imposing a burden on the user.
Thirdly, the disinfectant lamp is temporarily turned on when the disinfectant lamp is driven off for a predetermined time or longer. Therefore, the patent document in which the disinfectant lamp is driven on at regular intervals. Unlike No. 2, it is possible to prevent the disinfectant lamp from being unnecessarily turned on at an unnecessary timing. As described above, the service life of the disinfectant lamp generally becomes shorter as the frequency of switching on / off and the longer the lighting time, but according to the present invention, the disinfectant lamp is sterilized. By reducing the number of times the lamp is driven on and off and the lighting time is shortened, it is possible to appropriately suppress the shortening of the service life of the disinfectant lamp.

Fourth, even if the drive-off state of the sterilization lamp continues for the predetermined time or longer, there is an operation in which the hot water in the hot water distribution section of the sterilization device is replaced with other hot water during that period. Compared to the case where this is not the case, it is difficult for germs to grow in the hot water distribution section. In such a case, since the disinfectant lamp is not driven on, it is possible to more appropriately avoid the disinfectant lamp being driven on unnecessarily. On the other hand, in addition to the drive-off state of the sterilization lamp, if the hot water distribution section is not replaced for a predetermined time or longer, the sterilization lamp is temporarily turned on, so that germs in the hot water distribution section are not replaced. It is possible to appropriately prevent the growth of species.

The bath device provided by the second aspect of the present invention includes a hot water distribution section through which hot water in the bathtub can flow in and out, and a disinfectant lamp capable of irradiating the hot water in the hot water distribution section with light for disinfection. It is a bath device including a sterilizing device having a sterilizing device and a control unit for controlling the sterilizing device, and includes a hot water supply means capable of supplying clean water to the hot water distribution unit. When the drive-off state of the sterilization lamp continues for a predetermined time or longer, the control unit supplies clean water from the hot water supply means to the hot water distribution unit to replace the hot water in the hot water distribution unit. It is characterized by being configured.

According to such a configuration, the following effects can be obtained.
That is, if the drive-off state of the sterilization lamp continues for a predetermined time or longer, the hot water in the hot water distribution section of the sterilization device is replaced with clean water, so that the growth of various germs in the hot water distribution section can be appropriately prevented or prevented. It is suppressed. Therefore, similarly to the bath device provided by the first aspect of the present invention, the inside of the sterilization device is prevented from being contaminated by the growth of various germs, and the irradiation efficiency of the sterilization light for hot water is lowered. It is possible to solve this problem.
Further, since the operation of supplying clean water to the hot water distribution unit of the sterilizer is so-called automatic under the control of the control unit, it does not impose a burden on the user. Further, unlike the bath device provided by the first aspect of the present invention, the disinfectant lamp does not need to be driven on, so the frequency of switching the drive on / off of the disinfectant lamp is reduced, and the disinfectant lamp is driven. This is more preferable in extending the service life of the product.

In the present invention, preferably, even when the drive-off state of the disinfectant lamp continues for the predetermined time or longer, the hot water of the hot water distribution unit is replaced with another hot water during that period. In this case, the hot water supply means does not supply the clean water to the hot water distribution section, and the hot water supply means supplies the clean water from the hot water supply means to the hot water distribution section in the drive-off state of the disinfectant lamp. It is configured to be executed when any of the states without replacement of hot water in the hot water distribution section is continued for the predetermined time or longer.

According to such a configuration, even if the drive-off state of the sterilization lamp continues for the predetermined time or longer, the hot water in the hot water distribution section of the sterilization device is replaced with other hot water during that period. Therefore, when it becomes difficult for germs to grow in the hot water distribution section, it is possible to prevent the supply of clean water to the hot water distribution section from being unnecessarily executed. Therefore, it is more effective in saving water resources and reducing running costs.

In the present invention, preferably, when the clean water is supplied from the hot water supply means to the hot water distribution section, the disinfectant lamp is temporarily turned on.

The configuration corresponds to a configuration combining the main configurations of the bath device provided by each of the first aspect and the second aspect of the present invention. According to the above configuration, it is more thoroughly prevented that various germs grow in the hot water distribution part of the sterilizer and cause stains in this part.

In the present invention, preferably, the temporary drive-on operation of the disinfectant lamp or the supply of clean water from the hot water supply means to the hot water distribution unit is such that the drive-off state of the disinfectant lamp continues for a predetermined time. It is said that it can be executed at the timing delayed from the time when it was done.

According to such a configuration, it is possible to perform a temporary drive-on operation of the disinfectant lamp or a clean water supply operation to the hot water distribution unit, for example, at a timing requested by the user. When supplying clean water to the hot water distribution section, water circulation noise and drainage noise are generated, and it is possible to set such noise so as not to be generated at midnight, for example.

In the present invention, preferably, the bathtub is connected to the bathtub and is provided with a hot water circulation path for circulating hot water in the bathtub by a certain route by driving a circulation pump, and the sterilizing device forms the hot water flow section. The housing is connected to the middle of the hot water circulation path, and the disinfectant lamp is housed in the translucent tubular protective cover and arranged in the housing.

According to such a configuration, it is possible to appropriately perform the sterilization treatment of hot water in the bathtub while simplifying the overall configuration of the sterilization device and the like.

Other features and advantages of the present invention will become more apparent from the following description of embodiments of the invention with reference to the accompanying drawings.

It is explanatory drawing which shows an example of the bath apparatus which concerns on this invention. It is sectional drawing of the main part which shows the sterilizing apparatus used in the bath apparatus shown in FIG.

It is a flowchart which shows another example of the operation control executed in the bath apparatus shown in FIG.

Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

The bath device A shown in FIG. 1 is connected to the bathtub 1 via the bathtub 1 installed in the bathroom BR, the hot water circulation path 5 connected to the bathtub 1, and the external pipes 5a and 5b constituting the hot water circulation path 5. It includes a connected hot water supply device WH, a circulation pump P1 provided in the middle of the hot water circulation path 5, a sterilization device E, and a control unit 7 for executing operation control of the hot water supply device WH. In the figure, reference numeral 90 is an outer case of the hot water supply device WH.

The hot water supply device WH is, for example, an instantaneous gas hot water supply device, and has an automatic hot water filling function for the bathtub 1, a bath reheating function, and a general hot water supply function for the hot water tap 60 and the like. In addition, the sterilization treatment operation of hot water in the bathtub 1 can be performed by using the sterilization device E.

Specifically, in this hot water supply device WH, hot water flowing into the water inlet 2 from the water inlet 20 is sent to the heat exchanger 30 and heated by the burner 31. The heated hot water reaches the mixing valve 23 via the flow path 22 and is mixed with the unheated hot water flowing through the bypass flow path 21 at a predetermined mixing ratio to adjust the temperature. The general hot water supply to the hot water supply tap 60 is performed by the hot water that has passed through the mixing valve 23 circulates through the hot water supply channel 6 for general hot water supply.

In the automatic hot water filling operation to the bathtub 1, the on-off valve V1 provided in the hot water supply channel 50 for bath water supply is opened, so that the hot water that has passed through the mixing valve 23 flows from the hot water supply channel 50 for hot water supply to the hot water circulation path. It is done by flowing into 5. The hot water circulation path 5 has a configuration in which the internal pipes 5c and 5d of the hot water supply device WH and the heat exchanger 33 for reheating the bath are connected to the external pipes 5a and 5b connected to the adapter 10 of the bathtub 1. In the bath reheating operation, the circulation pump P1 is driven on, the hot water of the bathtub 1 is sent to the heat exchanger 33 via the hot water circulation path 5, heated by the burner 34, and then returned to the bathtub 1.

As shown in FIG. 2, the sterilization device E has a hot water inlet 41 and an outflow port 42, a housing 4 whose inside is formed as a hot water distribution section 40, and a sterilization lamp housed in the housing 4. 8. Two substantially cylindrical protective covers 81 and 82 for covering the disinfectant lamp 8 and caps 43a and 43b for closing the upper and lower openings of the housing 4 are provided. The inflow port 41 and the outflow port 42 of the housing 4 are connected to an intermediate portion of the internal pipe 5c of the hot water circulation path 5. The disinfectant lamp 8 is, for example, an ultraviolet lamp.

Both the protective covers 81 and 82 have translucency against ultraviolet rays emitted from the sterilizing lamp 8, and by driving the sterilizing lamp 8 to light up, the hot water of the hot water distribution unit 40 can be sterilized. .. On the other hand, the protective cover 81 is a waterproof member that prevents the disinfectant lamp 8 from coming into contact with the hot water in the housing 4, and is made of glass, for example. On the other hand, the other protective cover 82 is made of resin and is externally fitted to the one protective cover 81 through a gap. The protective cover 82 plays a role of preventing the fragments of the protective cover 81 made of glass from being scattered and flowing out to the hot water circulation path 5 in the unlikely event that the protective cover 81 is damaged. In the present embodiment, hot water also flows into the gap between the protective covers 81 and 82. However, it is also possible to make the protective cover 82 close to the outer peripheral surface of the protective cover 81 so as not to generate such a gap. In the sterilization treatment operation of the hot water of the bathtub 1, both the sterilization lamp 8 and the circulation pump P1 are driven on, and the hot water of the bathtub 1 is discharged to the hot water circulation path 5 and sent to the hot water distribution unit 40 of the sterilization device E. This is an operation of sterilizing the hot water and returning the sterilized hot water to the bathtub 1.

The control unit 7 is configured by using a microcomputer, and corresponds to the switch operation of the remote controllers 70 and 71 of the bathroom and the kitchen connected to the control unit 7 by communication, and operates the operation control and data of each part of the hot water supply device WH. Execute the process. The remote controllers 70 and 71 are provided with a plurality of operation switches 72, and any of the plurality of operation switches 72 is an operation switch 72 capable of switching between setting and canceling the sterilization processing control mode described later. It is said that. When the sterilization processing control mode is set, the control unit 7 performs the operation control described later, which will be described with reference to FIG. 3, for example. Further, the control unit 7 is configured to perform operation control for preventing the growth of various germs in the sterilization device E regardless of whether or not the sterilization processing control mode is set. The points will also be described later.

Next, the operation of the bath device A described above will be described.

First, when the sterilization processing control mode is set by operating any of the switches 70 and 71 of the remote controllers 70 and 71 in the bathroom and kitchen, for example, the control as shown in FIG. 3 is performed. In this control, basically, the sterilization processing operation in which both the sterilization lamp 8 and the circulation pump P1 are driven on for a predetermined time (for example, 30 minutes) is performed for a predetermined interval time (for example, 90 minutes). ) Is intermittently repeated. The start time or end time of the sterilization process control can be set in advance by a user or the like by operating a switch on any of the remote controllers 70 and 71 in the bathroom and kitchen.

To explain the example of FIG. 3 more specifically, in the figure, the time zone from 19:00 to 23:00 is the scheduled bathing time zone, and the time zone from 23:00 to 1:00 the next morning is the start of sterilization treatment. It is considered to be an acceptable time zone. After that, it is a time zone in which the sterilization treatment operation is intermittently executed. In the figure, 9 o'clock the next morning is set as the scheduled completion time of the sterilization process. As described above, the sterilization treatment operation is repeated with 30 minutes on and 90 minutes off as an interval period as one cycle, so the start time of the first removal treatment operation is the scheduled completion time of the sterilization treatment. It is calculated back from 9:00 the next morning and is set to 0:30. This first sterilization operation ends at 1 o'clock 30 minutes later, and then 90 minutes later, at 2:30, the second 30-minute sterilization operation starts. After that, the operation in which the sterilization processing operation is 30 minutes and the interval is 90 minutes is repeated a plurality of times, and the final sterilization processing operation is completed at 9 o'clock at the scheduled time. Therefore, after 9 o'clock, it is possible to use the hot water (remaining hot water) of the bathtub 1 for washing in a state where the sterilization treatment is completed.

On the other hand, apart from the sterilization processing control mode as described above, the control unit 7 is configured to also execute the operation control as shown in the flowchart of FIG.

That is, when the sterilization lamp 8 is driven off, the control unit 7 determines whether or not this drive-off state continues for a predetermined time (for example, 24 hours) or more (S1: YES, S2). When the sterilization treatment control mode is set and the sterilization treatment operation as shown in FIG. 3 is executed every day, the drive-off state of the sterilization lamp 8 does not continue for more than 24 hours, but the user If the sterilization treatment control mode is not set, the drive-off state of the sterilization lamp 8 may continue for 24 hours or more.

In the above determination, when it is determined that the drive-off state of the sterilization lamp 8 has continued for a predetermined time or longer, the hot water distribution unit 40 of the sterilization device E does not have to be replaced for the predetermined time or longer. It is also judged whether or not it is continued (S2: YES, S3). Here, the replacement of hot water in the hot water distribution unit 40 means removing the hot water from the hot water supply channel 50 for bath hot water supply by opening the on-off valve V1 such as filling the bathtub 1 with hot water, hot water, and hot water. This corresponds to the case where clean water (hot water that has entered the water inlet 20) is supplied in a predetermined amount or more to the hot water circulation channel 5 provided with the bactericidal device E. Further, it is also applicable when the hot water of the bathtub 1 flows into the hot water circulation path 5 by a predetermined amount or more by driving the circulation pump P1.

When the control unit 7 determines that the state in which the hot water in the hot water circulation path 5 has not been replaced continues for the predetermined time or longer, the sterilization lamp 8 is temporarily driven on and turned on. With the on-off valve V1 open, a predetermined amount of clean water flowing from the water inlet 20 to the hot water supply channel 50 for bath hot water is supplied to the hot water circulation path 5, and the hot water in the hot water distribution section 40 of the sterilizer E is replaced. (S3: YES, S4, S5). The total configuration of the hot water distribution path from the water inlet 20 to the hot water outlet 50 for bath water supply and the on-off valve V1 is an example of the "hot water supply means capable of supplying clean water to the hot water distribution section" in the present invention. Equivalent to.

In the above operation, the temporary drive-on time of the disinfectant lamp 8 is, for example, about 1 minute. However, the present invention is not limited to this, and the remote controllers 70 and 71 can be appropriately changed by operating a switch or the like. In the operation of supplying a predetermined amount of clean water to the hot water circulation path 5 with the on-off valve V1 open, it is not necessary to heat the clean water by the burner 31, and the clean water may remain unheated. The amount of clean water supplied to the hot water circulation path 5 is preferably substantially the same as the volume of the hot water circulation path 5 or the total volume of the hot water circulation path 5 and the hot water supply hot water supply channel 50.

At the time of supplying clean water to the hot water circulation path 5 described above, the residual hot water in the sterilizing device E flows out to the outside of the housing 4 and flows through the internal pipe 5d and the external pipe 5b. Therefore, preferably, as shown in FIG. 1, a three-way valve V2 is provided in the external pipe 5b so that the residual hot water is drained onto the drain pan 11 so as not to flow into the bathtub 1. Will be done. Further, instead of such a configuration, a drain valve 12 of the bathtub 1 having a remote controllable opening / closing operation is used, and when clean water is supplied to the hot water circulation path 5, the drain valve 12 is opened in advance. After setting the state, the residual hot water may be configured to flow into the bathtub 1.

According to the series of operations described above, when the hot water existing in the hot water distribution unit 40 of the sterilization device E is not replaced and the sterilization treatment is not performed for a predetermined time (for example, 24 hours) or more, The sterilization lamp 8 is driven on, and the sterilization treatment in the hot water distribution unit 40 is performed. Further, by supplying the clean water into the hot water distribution section 40, the hot water in the hot water distribution section 40 is replaced with the clean water. Therefore, the propagation of various germs in the hot water distribution unit 40 is appropriately prevented.
When the hot water is replaced, the user or the like may be notified by using the notification means provided in the remote controllers 70 and 71.

The sterilizing device E of the present embodiment has a structure in which hot water easily remains in the gaps between the two protective covers 81 and 82 shown in FIG. 2, but as described above, the sterilizing lamp 8 is driven on. And by supplying clean water, it is possible to appropriately discharge the residual hot water in the gap and disinfect the bacteria. Therefore, it is possible to enhance the effect of making it difficult for the surfaces of the protective covers 81 and 82 to become dirty due to the growth of various germs. Therefore, the ultraviolet transmittance of the protective covers 81 and 82 can be prevented from decreasing, and the sterilization processing ability of the sterilization device E can be maintained in an excellent state. Since the drive-on operation of the sterilization lamp 8 and the clean water supply operation in steps S4 and S5 are executed at the timing before the germs start to grow rapidly in the hot water distribution section 40 of the sterilizer E. It is excellent in efficiency, and has advantages such as reducing the number of times the disinfectant lamp 8 is lit to extend the service life of the disinfectant lamp 8 or saving clean water to keep the running cost low. Be done.

The temporary drive-on operation of the sterilization lamp 8 in steps S4 and S5 and the operation of supplying clean water to the sterilization device E are not necessarily executed immediately after the predetermined time (for example, 24 hours) has elapsed. However, it may be executed with a delay of an appropriate time. In particular, when the clean water supply operation of step S5 is executed, hot water flows through the hot water circulation path 5 and the like, and a sound of hot water flowing into the drain pan 11 or the bathtub 1 is generated. It is also possible to execute the operation at a timing that avoids the above.

The bath device A may be configured to perform operation control as shown in the flowcharts shown in FIGS. 5 and 6. In these figures, steps having the same contents as the flowchart shown in FIG. 4 are given the same step numbers, and duplicate description will be omitted.

In the operation control shown in FIG. 5, when the drive-off state of the sterilization lamp 8 continues for a predetermined time or longer,
The disinfectant lamp 8 is temporarily turned on (S1, S2: YES, S4). In this operation control, the operation of replacing the hot water of the hot water distribution unit 40 by supplying clean water to the sterilizing device E with the on-off valve V1 open is not executed, but the sterilizing lamp 8 is temporarily driven on. Therefore, it is necessary to appropriately prevent the growth of various germs in the hot water distribution section 40 of the sterilizer E, and appropriately prevent the protective covers 81 and 82 from becoming dirty due to the growth of the germs. Is possible.
Although the illustration will be omitted, in the operation control shown in FIG. 5, step S3 shown in FIG. 4 can be added as a condition for driving on the sterilizing lamp 8 in step S4.

In the operation control shown in FIG. 6, when the drive-off state of the sterilization lamp 8 continues for a predetermined time or longer, the on-off valve V1 is opened, clean water is supplied to the sterilization device E, and the hot water of the hot water distribution unit 40 is replaced. The operation is executed (S1, S2: YES, S5). In this operation control, the operation of driving on the disinfectant lamp 8 is not executed, but the residual hot water in the hot water distribution unit 40 is replaced with clean water, so that odorous germs may grow in the hot water distribution unit 40. This is prevented, and it is possible to obtain the effect intended by the present invention.
Although the illustration will be omitted, in the operation control shown in FIG. 6, step S3 shown in FIG. 4 can be added as a condition for executing the clean water supply operation in step S5.

The present invention is not limited to the contents of the above-described embodiments. The specific configuration of each part of the bath device according to the present invention can be variously redesigned within the scope intended by the present invention.

The sterilization device can have a configuration different from that of the sterilization device E shown in FIG. 2, and for example, the protective cover 82 may be omitted. Further, as the housing of the sterilizer, a tubular housing in which the entire or part of the peripheral wall portion is made of a translucent material is used, and the inside of this housing is used as a hot water distribution part and is removed to the outside of this housing. By arranging the fungus lamp, it is possible to irradiate the hot water in the housing with light for sterilization from the outside of the housing.

In the above-described embodiment, the sterilization treatment operation as shown in FIG. 3 is executed as a normal sterilization treatment operation for hot water in the bathtub 1, but the present invention is not limited to this. For example, a motion sensor is provided in the bathroom remote controller 70 or the like, and the sterilization lamp 8 is driven on at the timing when the bather's exit from the bathroom BR is detected by the motion sensor. Is also possible. Of course, unlike these, it is also possible to configure the bathtub 1 to be sterilized only when the user operates a specific switch using either the remote controller 70 or 71. Is. The present invention does not ask what timing or operation the normal sterilization treatment operation is performed.
